Fractures and dislocations of the pelvis are rare but serious conditions. Anterior displacements tend to recur due to muscle action, while lateral displacements can be palpated through the rectum or vagina. Posterior displacements present an abnormal prominence in the gluteal cleft. Symptoms depend on the region injured and extent of soft tissue damage. Complications like urethra or bladder rupture are common.

Symphysis pubis separation may result from indirect violence or childbirth trauma. Pain and weight-bearing issues are common due to counter-arch dissolution. Fractures of the anterior portion of the pelvic ring often involve both rami of the pubis, causing deformity detectable by palpation.
Fractures in lateral portions of the pelvis near the acetabulum can result from trauma through the femur head or neck. Symptoms include shortening and immobility of the lower extremity, abnormal mobility, and crepitus upon manipulation. When the acetabulum is fractured, the patient may experience severe pain and inability to bear weight.
Transverse fractures of the sacrum are rare but serious, often accompanied by rectal injury and nerve damage leading to paralysis or shock.
Key Takeaways
- Anterior displacements tend to recur due to muscle action.
- Lateral displacements can be palpated through the rectum or vagina.
- Symphysis pubis separation causes pain and weight-bearing issues.
Practical Tips
- Use a short anesthetic for thorough examination without causing additional trauma.
- Palpate the pelvis systematically to detect fractures and articular displacements.
Warnings & Risks
- Avoid further injury during palpation as manipulation may cause more serious damage.
- Severe pain, shock, and inability to walk are common symptoms of pelvic injuries.
Modern Application
While modern medical imaging has improved diagnosis accuracy, the historical techniques for identifying pelvic fractures through palpation and symptom recognition remain crucial. Understanding these methods can be invaluable in emergency situations where advanced diagnostic tools may not be available.
Frequently Asked Questions
Q: What are common symptoms of a fractured pelvis?
Common symptoms include severe pain, inability to walk, shock, shortening and immobility of the lower extremity, abnormal mobility, and crepitus upon manipulation.
Q: How is symphysis pubis separation diagnosed?
Symphysis pubis separation can be felt or seen in many instances. A separation over one and a half inches often indicates rupture of the anterior sacro-iliac ligaments or fracture elsewhere in the pelvic ring.
Q: What complications are associated with transverse fractures of the sacrum?
Transverse fractures of the sacrum may cause rectal injury, nerve damage leading to paralysis, and severe pain radiating up the back and down the thighs. Shock is often pronounced in such cases.
